Methods

availableNetworks() → List<BtcNetwork>

Returns network providers built from dashboard metadata and host configuration.

broadcastTransaction(String signedTransactionHex, [BtcNetwork? network]) → Future<String>

Broadcasts a signed transaction and returns its transaction ID.

configureNetworks(List<BtcNetwork> networks) → void

Sets host REST endpoints. The first host network remains the default. Dashboard networks are resolved when used.

getBalance(String address, [BtcNetwork? network]) → Future<String>

Returns the confirmed balance in satoshis.

getFeeEstimates([BtcNetwork? network]) → Future<List<BtcFeeEstimate>>

Returns fee rates by confirmation target, in satoshis per virtual byte.

getUtxos(String address, [BtcNetwork? network]) → Future<List<BtcUtxo>>

Returns the unspent outputs for an address.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

publicKeyForAddress(String address) → String

Public key from the credential's walletAdditionalAddresses, used to construct a PSBT.

signPsbt(String fromAddress, String unsignedPsbt) → Future<String>

Signs all owned PSBT inputs without input-index or sighash restrictions. Returns the partially signed PSBT.
